Science doesn't have to be
complicated, expensive or use specialized laboratory equipment.
There are great science projects that can be performed using common
household items.

Whether you are a parent or a student trying
to find an idea for a science project, a teacher looking for ideas
for the classroom, or a science enthusiast who enjoys the delight of
experimentation, you'll find what you're looking for in this book.

Hang the Wheel of
Better Behavior
on your kitchen wall, and the atmosphere in your home will change overnight. It's
guaranteed! Watch the dramatic changes as homework gets done, clothes get
picked up, arguing stops...in short, the Wheel produces great kids and a stress
free environment! The mere presence of the Wheel will have a marked effect on
your kids. Chances are, you'll seldom even have to spin it!

Sound is a type of energy made by vibrations.
When any object vibrates, it causes movement in the air particles.
These particles bump into the particles close to them, which makes
them vibrate too causing them to bump into more air particles. This
movement, called sound waves, keeps going until they run out of
energy. If your ear is within range of the vibrations, you hear the
sound.

In wind instruments, like the flute and trumpet, vibrating air
makes the sound. The air particles move back and forth creating
sound waves. Blowing across a flute's blow hole sets up Slinky-like
waves in the tube. In the clarinet, a vibrating reed (a thin piece
of wood set in the mouthpiece) gets the waves started. Different
pitches are played by pressing keys that open or close holes in the
tube making the air column inside the tube longer or shorter. Longer
air columns produce lower pitches.

How do String Instruments make sound?

Stringed instruments are played by pressing the fingers down on
the strings. This pressure changes the strings' length, causing them
to vibrate at different frequencies and making different sounds.
Shortening a string makes it sound higher. Strings produce different
sounds depending on their thickness.

Tie a piece of thread to some tissue paper. Put on some loud music and hold the thread in front
of a loud speaker. The vibrations should make the tissue paper shake.

Water Chimes
Fill a set of glasses with different amounts of water. Eight glasses are enough to create an octave
of eight notes. Strike each glass. Do they all make the same note? Changing the amountof water will change the note. The amount of water in the glass changes the pitch of the sound wave.

Can you use the notes to play a simple tune?

Awesome Experiments In
Light & Sound

Using easy-to-find
materials, you can perform dozens of awesome
experiments. These incredible investigations will change
the way you look at and listen to the world around you!

It's music to your
ears--but why does one instrument make a different sound than
another? Each of these delightfully illustrated safe and
"sound" experiments uses ordinary materials to teach
fabulous facts about the bangs, slaps, whistles, claps, and
harmonies in our world.

Yes sound can travel under the water. It
moves four times faster through water than through the air. It can
travel such long distances that whales can hear each other when
they are nearly a hundred miles apart.

2. Is there sound on the moon?

No, there is no sound in space. Sound needs
something to travel through like air or water.
